GUARD-RAIL FOR STREET-CARS.

Specification of Letters Patent.

ratented April 24, 1906.

Application filed December '7, 1905. Serial No. 290,715.

lb all 1072 0712, it may concern:

Be it known that I, EDWARD P. DAN- DRIDGE, a citizen of the UnitedStates,resid ing at Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented new and useful Improvements inGuard-Rails for Street-Cars, of which the following is a specification.

This invention relates to movable guardrails of the type employed onstreet-cars, being especially directed to means for supporting andmoving the rail, and has for its objects to produce a comparativelysimple inexpensive device of this character whereby the rail may bereadily raised or lowered as circumstances require, one wherein themechanism may be conveniently manipulated for moving the rail, and onein which the boxes or casings for holding the rail-operating mechanismare adapted for ready application to either end or side of the car.

With these and other objects in view the invention comprises the novelfeatures of construction and combination of parts more fully hereinafterdescribed.

In the accompanying drawings, Figure 1 is a side elevation, partly invertical longitudinal section, of a car equipped with a guardrailembodying the invention. Fig. 2 is an end view of the car. Fig. 3 is afront elevation of one of the casings and its contained mechanism ndththe front wall or cover removed. Fig. 4 is a vertical section taken onwith the removable cover in place. Fig. 5 is a side elevation of one ofthe guardrails. Fig. 6 is a detail perspective view of one of thebearing-brackets.

Referring to the drawings, 1 designates a car of usual constructionhaving end walls 2 provided with vertical guide openings or slots 3,designed to receive and accommodate the ends of the guard-rails 4.,which extend longitudinally of and at the sides of the car in the usualmanner and for the usual purpose.

Extended longitudinally of the car and respectively above theguard-rails 4 is a pair of rotary shafts 5, journaled at their ends inbearing-openings 6, provided in the normally upper ends of boxes orcasings 7, attached to the outer faces of the end walls 2 and coveringthe guide-slots 3, it being noted that a pair of the bearing-openings 6is provided in each of the boxes 7 for a purpose which will hereinafterappear, while applied to the ends of the shafts 5 are suitableoperating-cranks 8.

T he boxes or casings '1, which are identical in construction, eachcomprise side walls 9 and a removable outer wall or cover 10, therebeing extended centrally and longitudinally through the box at itsnormally inner face a bearing member or strip 11, spaced from the walls9 to provide a pair of guide openings or slots 12, one of whichregisters with the corresponding opening 3 in the end wall of the carand receives the adjacent end of the guard rail 4, it being noted inthis connection that by providing each of the boxes with a pair ofbearing-openings 6 and a pair of guide-slots 12 the boxes are adaptedfor interchangeability and to be applied to either end wall of the carand at either side of the latter. Provided on the side walls 9 areperforated cars 13, designed for the reception of fastening members, bymeans of which the boxes are secured to the car.

J ournaled in the upper end of eachbox7 is a I plurality of guiderollers or pulleys 14, 15, and 16, having arranged for travel thereon aflexible hoisting element or cable 17, connected at one end with theadjacent end of the guard-rail 4 and at its other end with and to bewound upon the corresponding shaft 5, it being noted that the cable 17is extended over the pulleys l4 and 15 and thence backward over theintermediate pulley 16, from which latter a direct pull is exerted uponthe cable by the shaft.

Connected with each shaft at suitable points between its ends is a pairof intermediate operating elements or cables 18, connected at theirlower ends with the guardrail 4 and at their upper ends with and to bewound upon the shaft, which latter is sustained at a central pointbetween its ends by means of a bearing member or bracket 19, bolted tothe adjacent car-standard and having a horizontal portion or arm 20terminating at its outer end in a semicircular seat 21 for the receptionof the shaft.

In practice when it is desired to raise the guard 41 to an unobstructingposition the corresponding shaft 5 is rotated though the medium of oneof the cranks 18 for winding the cables 17 and 18, thus raising theguard in a manner which will be readily understood, it being apparentthat the guard will during such movement be guided in the slots 3 and12, while, on the other hand, the cables will unwind freely to ermit ofthe guard being moved downward to normal active position. It may bementioned in this connection that when the guard is in elevated positionthe crank-handles 8 serve as weights to counterbalance the guard andmaintain the shafts against rotation, this function of the handles beingfacilitated owing to the specific arrangement of the cables 17 on theirguide-rollers.

From the foregoing it is apparent that I produce a simple deviceadmirably adapted for the attainment of the ends in view, it beingunderstood that in attaining these ends minor changes in the detailsherein set forth may be resorted to without departing from the spirit ofthe invention.

Having thus fully described my invention, what I claim as new is 1. In adevice of the class described and in combination with a car having anend wall provided with a vertical guide-opening, a boX or easingattached to the wall and having a pair ofguide-openings, one of saidopenings being in registry with the guide-opening in the car-wall, aguard-rail having its end arranged for movement in the guide-open ings,a rotaryoperating-shaft j ournaled at one end in the casing, a flexiblehoisting element terminally engaged with the shaft and guardrail, and aplurality of guide-rollers over which the cable travels.

2. In a device of the class described and in combination with 'a carhaving an end wall provided with a vertical guideo, ening, a guard-railhaving its end arranged or movement in said opening, ,a casingattachedto the carwall over the opening, an operatingshaft journaled inthe-casing, a rotary guide, and a flexible hoisting element arranged'fortravel on said guide and terminally engaged with the shaft and ra-i'lQ ii In testimony whereof-:I afiix my signature -40 in presence of't wo"witnesses.
